ATTR_REMOVE(3) XFS Compatibility API ATTR_REMOVE(3)
attr_remove, attr_removef - remove a user attribute of a
filesystem object
#include <attr/attributes.h>
int attr_remove (const char *path, const char *attrname, int flags);
int attr_removef (int fd, const char *attrname, int flags);
The attr_remove and attr_removef functions provide a way to
remove previously created attributes from filesystem objects.
Path points to a path name for a filesystem object, and fd refers
to the file descriptor associated with a file. If the attribute
attrname exists, the attribute name and value will be removed
from the filesystem object. The flags argument can contain the
following symbols bitwise OR'ed together:
ATTR_ROOT
Look for attrname in the root address space, not in the
user address space. (limited to use by super-user only)
ATTR_DONTFOLLOW
Do not follow symbolic links when resolving a path on an
attr_remove function call. The default is to follow
symbolic links.
attr_remove will fail if one or more of the following are true:
[ENOATTR]
The attribute name given is not associated with the
indicated filesystem object.
[ENOENT]
The named file does not exist.
[EPERM]
The effective user ID does not match the owner of the file
and the effective user ID is not super-user.
[ENOTDIR]
A component of the path prefix is not a directory.
[EACCES]
Search permission is denied on a component of the path
prefix.
[EINVAL]
A bit was set in the flag argument that is not defined for
this system call.
[EFAULT]
Path points outside the allocated address space of the
process.
[ELOOP]
A path name lookup involved too many symbolic links.
[ENAMETOOLONG]
The length of path exceeds {MAXPATHLEN}, or a pathname
component is longer than {MAXNAMELEN}.
attr_removef will fail if:
[ENOATTR]
The attribute name given is not associated with the
indicated filesystem object.
[EINVAL]
A bit was set in the flag argument that is not defined for
this system call, or fd refers to a socket, not a file.
[EFAULT]
Attrname points outside the allocated address space of the
process.
[EBADF]
Fd does not refer to a valid descriptor.
On success, zero is returned. On error, -1 is returned, and
errno is set appropriately.
